Other ID: HE0806; H-2-08-AR, H-02-08-AR
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Deborah Hutchinson
Affiliate Investigator(s): Jon Childs, USGS-Menlo Park
Information Specialist(s): William Danforth
Data Type(s): Sonar: Multibeam, Seismics: Sub Bottom Profiler, Sampling: Biology, Location-Elevation: Navigation, Imagery: Photo, Environmental Data: CTD, Electro-Magnetic: Gravity
Scientific Purpose/Goals: Collect bathymetry, chirp sub-bottom, and gravity data as well as break ice for a second ship (LOUIS S. ST. LAURENT) as part of delimiting the boundary of the U.S. extended continental shelf in the Eurasian Basin of the Arctic Ocean.
Start Port/Location: Barrow, AK
End Port/Location: Barrow, AK
Start Date: 2008-09-06
End Date: 2008-10-01
Equipment Used: DGPS, Gravity meter (wh), SBE 9 CTD, SeaBeam 2112, Digital camera, Knudsen CHIRP Sub-bottom Profiler, Plankton nets
Information to be Derived:
Summary of Activity and Data Gathered: There were 5146 km of tracklines (multibeam, sub-bottom and gravity). Total area imaged was 39,311 km2 with the SeaBeam 2112. 11 stations were occupied for CTD and 10 stations for phytoplankton analysis.
